EXPLORE SCIENTIFIC Solarix Solar Filter Film A4

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

The BRESSER JUNIOR Astro Planetarium quickly transforms your ceiling into a starry sky. And then it’s time for you to go exploring: This home planetarium projects over 8,000 stars and 61 named constellations using 2 projection discs and a bright LED, bringing the universe into your home. Ever curious about the constellations visible on your birthday? Why not have a look? Just set the date and a time between 8 PM and 2 AM, because during this time there will always be stars in the sky. Then just switch on the children's planetarium and the night sky of your birthday lights up above you. For the best experience, maintain a 2-meter distance from the ceiling. This allows the projection to cover a substantial area of approximately 1.6 x 2.1 metres. A focusing wheel ensures the celestial display is crystal clear. This is not just for special occasions like Christmas or birthdays; it's a year-round gateway to the stars. Use the star projector to enjoy the night sky indoors If you've ever used a telescope, the most crucial tool for stargazers, you know that clear skies are essential. Cloudy skies can obscure your view of the heavenly bodies. With this home planetarium, however, weather is no impediment. Rain or snow, your exploration of astronomy continues indoors. Thanks to its built-in motor, the projected sky rotates automatically. A counter-clockwise rotation mimics the natural movement of the northern hemisphere, while a clockwise rotation aligns with the southern hemisphere's pattern. Choose from 6 speed settings to tailor your experience. The shooting star mode adds a dash of magic, bringing meteor trails across your ceiling. Drift off to sleep under the stars There's something incredibly soothing about falling asleep under a starlit sky. The sleep mode turns off the home planetarium automatically after 30 or 60 minutes. For longer enjoyment, let it run normally, and it will switch off after 2 hours to conserve energy. You'll likely be deep in dreams of cosmic adventures by then. Turn your home into a place for celestial explorations with the BRESSER JUNIOR Astro Planetarium. FEATURESStar projector suitable for children aged 14 and up Shooting star function Automatic shut-off (after 30, 60, or 120 minutes) Projection area of 1.6 x 2.1 metres (at a 2-metre distance) 1 bright, white LED Motion-enabled projection through dual motors offering 6 speeds Focusing wheel for clear images Night sky simulation on walls or ceilings, adjustable for specific dates and times More than 8,000 celestial bodies and 61 constellations on 2 projection discs Maximum projection distance: 3 metres SCOPE OF DELIVERYAstro planetarium 2x projection discs 3x AA batteries Instruction manual

Instruction manual

Fast 90 mm high-performance astrograph for demanding astrophotographers and observers with 5 lens elements in 5 groups. Due to the complex optical structure with five lens groups and five elements (quintuplet), including two SD (Super ED) lenses and an ED lens (Extra-low Dispersion) , a virtually aberration-free optical system was created. This revolutionary astrograph is compatible with a full-frame digital DSLR or an even larger 44x33 mm camera. The 90 mm astrograph with fast aperture ratio delivers exceptionally sharp, high-contrast and small point stars from the centre to the corners of the field of view. In addition, it is also ideal for visual observation with a very large field of view but also for planetary observation with high magnification. The VSD90ss is designed so that there is a "long peak range" in the adjustment accuracy of the sharpness, so that photographers can always achieve satisfactory results in astrophotography. Even if the focus is not quite precise, round and sharp stars are still shown throughout the entire image field. Illumination without vignetting In most cases, an astrograph also produces optical vignetting (a gradual decrease in light rays towards the edge of the image) This is mainly caused by rear lenses being shaded by the front lenses. Because of this darkening, it is relatively normal for the photographer to have to further edit the image after taking the picture and also have to do some additional so-called flats before taking the picture. To solve this problem, the VSD90ss uses wide aperture lenses in the rear elements, securing over 90 % of the light volume at the edge of the 60 mm image circle. Since the light intensity is uniform throughout the entire image field of the VSD90ss, there is no need for complex technology to prevent edge darkening. The VSD90ss is coated with the most modern coatings of extremely high reflectivity. These coatings have been specifically developed to optimize the properties of each individual lens element without degrading contrast and light intensity across multiple lenses. Numerous gradations of light bring beautiful point-like stars into the image field The low optical vignetting ensures sufficient illumination and thus eliminates the asymmetric flare caused by bright, diffraction-limited stars. It prevents stars at the edge of the 60 mm image circle from exhibiting deformations such as comets, astigmatism or coma. Since the illumination of the image field is relatively similar from the center to the edge of the image, you can expect excellent star imaging. Please note: *Depending on the recording system used, mechanical vignetting can still occur due to the camera body or incorrect adapters. 96.7％ Strehl for impressive visual observations The VSD90ss offers a flattened large field of view with a low magnification wide angle eyepiece. Even with a high-quality wide-field eyepiece with a large field of view, you can get sharp images of stars in the entire field of view when visually observing! In the centre of the field of view, a Strehl intensity of an impressive 96.7% is achieved at visible wavelengths. This Strehl ratio exceeds that of the SD81SII apochromat at 95.7%, which is known for its excellent optical properties, and this also works excellently when observing the moon and planets at high magnification. The versatile large and stable focuser The VSD90ss has a large focuser with a diameter of 87.5 mm to make optimal use of the large illumination field of 60 mm. With the large extension that is compatible with many accessories, it is perfect for astrophotography up to large format or 35 mm full frame DSLR cameras. Thanks to its precise manufacturing, it is also suitable for very heavy cameras without tipping. The precision locking lever of the eyepiece extension The focuser's extension tube has a locking lever that holds the extension tube firmly in position even when using heavy cameras such as large format cameras or CCD cameras with a large sensor. The locking lever clamps the rack gear to the extension barrel so that the viewing angle or focus on your camera does not shift. Compatible with motor driven focusers An optional two-speed motor focuser (not included) is available for the VSD90ss to provide sensitive focusing. An EAF (Electronic Automatic Focuser) from ZWO or equivalent can also be retrofitted. Optional VSD Reducer for even faster results The tried and tested optional VSD reducer, which was also used on the predecessor, the VSD 100, is also compatible with the VSD90ss. The photographer gets even faster results in astrophotography with an aperture ratio of 1:3.9.
